4.2 Terminal rating Inputs
Mains supply: The input current for the mains supply is dependent on the operating
status of the LME7
Under voltage UMains 120 V UMains 230 V
 Safety shutdown from the operating
position takes place should mains
voltage drop
≤AC 75 V ≤AC 165 V
 Restart is initiated when mains
voltage exceeds
≥AC 100 V ≥AC 195 V
The remote lockout reset (terminal X2-03 pin 1), control thermostat, or limit
thermostat (terminal X5-03 pin 1), load controller (terminal X5-03 pin 2 / pin 3),
POC/CPI (terminal X2-02 pin 4), pressure switch (terminal X5-01 pin 2), air pressure
switch (terminal X3-02 pin 1), and actuator (terminal X2-09 pin 4) status inputs for the
contact feedback network are used for system supervision and require mains-related
input voltage
 Terminal X3-04 pin 1 and pin 2:
Safety loop input
See Terminal rating outputs
 Input currents and input voltages
- UeMax UN +10% UN +10%
- UeMin UN -15% UN -15%
- IeMax 1.5 mA peak
(peak value)
1 mA peak
(peak value)
- IeMin 0.8 mA peak
(peak value)
0.5 mA peak
(peak value)
 Contact material recommended for
external signal sources (air pressure
switch, pressure switch-min,
pressure switch-max, etc.)
Gold-plated silver contacts
 Transition / settling behavior /
bounce
- Perm. bounce time of contacts
when switching ON/OFF
Max. 50 ms
(after the bounce time, the contact must
stay closed or open)
 UN AC 120 V AC 230 V
 Voltage detection
- ON >AC 60 V >AC 120 V
- OFF <AC 40 V <AC 80 V
Terminal X65: Analog input DC 0...10 V / DC 0/4...20 mA / 0...135 Ω
